3M 7010328217 Abrasive Belt 118x3 Inch Aluminum Oxide

Product Description

The 3M 7010328217 is a Trizact 307EA coated abrasive belt designed for intermediate finishing and fine polishing on metal surfaces. It uses microreplication technology in which micron-graded aluminum oxide mineral is formed into uniform three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear down during use, fresh, sharp mineral is continuously exposed. This self-renewing cutting action delivers a consistent cut rate and a predictable, fine surface finish over the full life of the belt. The belt measures 118 inches in length and 3 inches in width and weighs 0.35 pounds.

This belt is suited for industrial and manufacturing environments where repeatability and surface finish consistency are critical. It is commonly used in robotic and automated grinding and finishing lines, as well as manual applications on contoured metal parts prior to plating, buffing, or coating operations. The flexible rayon backing conforms to curved and contoured workpiece surfaces, making it a practical choice for finishing complex geometry parts in metal fabrication and precision manufacturing shops.

Key Features

• Microreplication technology forms aluminum oxide into uniform abrasive pyramids for consistent, self-sharpening performance
• Fresh mineral is continuously exposed as pyramids wear, maintaining cut rate throughout belt life
• Runs cooler than conventional abrasives, reducing heat buildup on workpiece surfaces
• Flexible rayon cloth backing conforms to contoured and complex surface geometries
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Suited for robotic and automated finishing applications requiring predictable, repeatable results

Compatibility

Designed for use on belt grinders and finishing machines that accept 118-inch by 3-inch abrasive belts in industrial metal finishing, fabrication, and manufacturing applications.

Installation Notes

This belt should be installed by qualified personnel familiar with abrasive belt equipment. Ensure the machine is fully powered down and locked out before changing belts. Verify that belt tracking and tension are properly set according to the machine manufacturer guidelines before resuming operation. Inspect the belt for damage or wear before each use and replace if the backing shows cracking or the abrasive surface is glazed or worn through.
